This procedure assumes that:
you are installing into an existing VMware vSphere deployment which has pre-configured networks and VLANs; this procedure does not cover setting up a VMware vSphere deployment from scratch
you are upgrading an exisiting downlevel deployment for MMT CDMA.
you have deployed a SIMPL VM, unpacked the uplevel CSAR, and prepared an uplevel SDF.
This procedure does require a maintenance period. When integrating into a live network, it is recommended to implement measures to mitigate any unforeseen events.
|Refer to the SIMPL VM Documentation for details on the commands mentioned in the procedure.|
See CSAR EFIX patches to learn more on the CSAR EFIX patching process.
csar update --vnf mmt-cdma --sdf <path to SDF>.
This will validate the uplevel SDF, generate the uplevel Terraform template, and upload the uplevel image.
The following will occur one MMT CDMA node at a time:
The downlevel node will be quiesced.
The uplevel node will be created and boot up.
The VM will automatically start applying configuration from the files you uploaded to CDS in the above steps. During this phase, the status of the VM in MDM will be Orange.
Once configuration is complete, the status will change to Green, and the node will be ready for service. At this point the
csar updatecommand will move on to the next MMT CDMA VM, or report that the upgrade of the MMT CDMA was successful if all nodes have now been upgraded.
To perform a canary upgrade, run
If the upgrade has brought up uplevel VMs to replace the downlevel VMs, then the uplevel VMs can be rolled back to the downlevel VMs.
To rollback, repeat step 1 with the downlevel MMT CDMA CSAR and downlevel SDF,
--skip pre-update-checks flag to the
csar update command.
--skip pre-update-checks flag allows rollbacks when a node is unhealthy.
If the upgrade has failed to bring up the uplevel VMs or the rollback has failed to bring up the downlevel VMs,
then you must redeploy the downlevel VMs.
csar redeploy --vnf mmt-cdma --sites <site> --sdf <path to SDF>.
When the downlevel VMs are quiesced, they upload some diagnostics to CDS. These may be useful if the upgrade or rollback fails.
To get these diagnostics, follow instructions from Retrieving Initconf and Rhino logs with export-log-history.
If you are upgrading a full set of VMs, go to Rolling CSAR EFIX patch SMO nodes on VMware vSphere, otherwise, verify your MMT CDMA upgrade here: Verify the state of the nodes and processes.
